Steve’s Blog – Board Repair Guide

I’m ashamed to admit that up until now I’d never done a proper board repair.  I usually just let the crack dry, stuff it up with suncure and hope for the best.  For the past few days we’ve been under Nate’s tutelage learning the basics of repairing boards with fiberglass and resin.  Hopefully this comes in handy for you all when your board inevitably gets dinged up.

You’ll Need:

· Sandpaper (fine and course grain)

· A measuring cup

· Epoxy resin

· Catalyst

· Q-cell powder

· Fiberglass cloth

· At least 2 empty containers (you can cut plastic water bottles in half for this)

· Plastic cards for spreading the mixture

1. Drying and Sanding

After letting the foam dry under the sun, sand the ding or hole around the edges so that the edges slope inwards toward the hole.  This way the resin will dry over the entire ding and there won’t be any cracks left behind.  Using a block sander works best for broad strokes.  You can do a simple test to see if you’ve sanded enough by pressing down on the glass around the ding.  The glass should give under the pressure of your fingernail.  You should also be able to see the grain of the fiberglass cloth by the time you’ve sanded enough.

The edges are sanded to taper inwards toward the hole.

2. Cut Up Fiberglass Cloth

Cut the fiberglass with the grain, that way the edges won’t fray as much.  Cut each piece of fiberglass a little bit oversized so that it overlaps the edges of the ding.

3. Mixing Filler

To mix the filler you’ll need epoxy resin, catalyst, and Q-Cell powder.  Make sure you a container ready to put the mixture into.  First measure out three parts resin, dump it into your container.  Then measure out one part catalyst and add it in.  The measurements should be as exact as possible so it’s best to use a measuring cup.  Start stirring the solution until it’s thoroughly mixed.  Finally, mix in the Q-Cell powder a bit at a time.   The powder will emulsify the solution.  Keep stirring and mixing in powder until the solution is the consistency of cookie dough.

4. Spread the Filler

Using a credit card, spread some filler over the hole or ding and then even it out.

Yup, spread the filler with yo’ credit card.

5. Mix the Resin

For the resin you mix three parts epoxy resin to one part catalyst.  Don’t add any Q-Cell.

6. Glass on the Fiberglass Cloth

First spread some resin over the filled hole and then place your precut piece of cloth on top.  Pour on a little more resin and spread it evenly using a credit card.  Make sure that the cloth is saturated with resin and that the resin is evenly spread across the cloth.  The cloth should turn clear and bond to the board when the resin is applied correctly.  If you have multiple jobs then try and do this quickly because the resin hardens fast.

Spread the resin evenly.

7. Let Dry and Sand

The resin will take about a day to dry completely.  After its dry you can sand down any uneven bumps in the hardened resin.  At this point the dings in your board should be sealed and your board ready to ride.

Sand it and that’s it.
